[Feature Request] IINA Support

[george-emerald]

I'd like to request a simple intergation of IINA player. I understand that it would take a lot of development to fully support it as well as this supports mpv, but I'm asking for a very rudimentary implementation. Just the ability to feed the link to IINA. No need to properly commynicate with Plex. I'm perfectly fine marking stuff as watched on my own. It's just that mpv is very iffy with HDR support as it's hard to stop it from tonemaping. Is it as simple as setting an external player and feeding it the IINA binary?
